Near-freezing temperatures, wind and rain across the Bay Area on Thursday could include snow at peak elevations and thunderstorms elsewhere, complicating commutes by the end of the week.

Several communities recorded temperatures in the 30s early Wednesday, including a brisk 30 degrees in Santa Rosa, and conditions are expected to get even cooler as a cold front moves into the region, according to the National Weather Service.

Showers were projected to start in the North Bay around 10 p.m. Wednesday and increase through the night as the storm moved south.

“This system is fairly cold,” said Carolina Walbrun, a meteorologist with the weather service.
